So, I've managed to compile the necessary modules, install ALSA, and unmute the sound device I want to use. It shows up in /proc/asound/cards, and the master and PCM are both unmuted in alsamixer. ALSA is set to start during boot.

I'm at a loss as to what I should try next, so I'll just post some relevant info in hopes that someone can help me

I've tried running speakertest on all 3 sound devices, and still nothing. Really the only one that should matter is hw:0:0, because that is the analog output of the card that I want to use, but I tried all of them regardless.
